The macro_pka_results Script

The macro_pka_results script can be used for a variety of post-processing actions on the results of a Macro-pKa calculation. The script assumes a set of protonated and deprotated tautomers and conformers have been prepared in appropriately named files of the form charge_*.mae, where the index refers to the total charge relative to the input structure referenced in the input file. The structures will be used as-is without further geometry optimization or QM calculations. Post-processing takes a few seconds.

Process results at a different pH

You can calculate macro-pKa at a different pH, as well as see the breakdown of tautomer populations at the relevant charge transitions, by using the following command:

$SCHRODINGER/utilities/macro_pka_results -jobname <JOBNAME> -pH <X>

Process results with your own training data

To use a different set of training data to apply empirical corrections instead of the default, use the following command:

$SCHRODINGER/utilities/macro_pka_results -jobname <JOBNAME> -training_data <training.mae>

Process results with the Jaccard similarity method

To process the results using the Jaccard similarity method for empirical corrections , use the following command

$SCHRODINGER/utilities/macro_pka_results -jobname <JOBNAME> -use_jaccard
